| Hello, all. I know I don't post here much 'cause I'm more of a space fan... but I just wanted to ask you all for some help. My 8th grade science teacher assigned us a project in which we have to make and race a model solar car. So, because of my (...) (21 years ago, 19-Apr-03, to lugnet.technic)

| Ahh, thanks guys. I've tried larger wheels, and even though they look funny, they work the best- a lot better, even now in late afternoon. And I've added more torque using a larger gear, which makes it more powerful. (URL) digital camera movie (...) (21 years ago, 20-Apr-03, to lugnet.technic)
